Definitions

  • the present invention concerns improved spectacles with mounting and lenses interconnected by strap according to the preamble of the main claim 1.
  • Technological background In the technical field of reference it is known to produce spectacles in which the lenses are retained on mountings including lens-holding rims which completely or only partially surround the lens, by means of strap interconnecting means.
  • a resiliently flexible strap is provided, customarily of nylon, arranged to surround sections of the lens edge and to be engaged in corresponding holes in the mounting, and also capable of being tensioned so as to render the mounting and the lenses firmly connected to one another.
  • a known type of such mountings for spectacles provides, for each lens, a mounting member arranged to partially surround the lens and a connecting strap extended to encompass the remaining edge part of the lens, coupling means being provided for securing the strap at opposed lateral regions of the lens, in particular in the lug region and the region of the intermediate nasal support bridge. Provision is also made for the interposition of a resilient gasket, for example produced by a separate and different second filiform member, between the mounting member and the facing lens edge, constituting a yielding supporting cushion between the lens and the. mounting, capable of preventing possible breakage of the ' lens when locking same on the mounting, as a result of tensioning of the connecting strap.
  • a principal aim of the present invention is to provide spectacles with mounting and lenses interconnected by strap, in which the mounting of the lenses on the mounting is simplified and facilitated, with a reduced number of components necessary, and consequently of assembly operations required.
  • Another aim is that of simplifying the structure of the mounting arranged to receive lenses interconnected by strap, limiting or eliminating the provision of coupling means on the mounting for securing the connecting strap with relative tensioning.
  • Yet another aim is that of providing spectacles in which the same strap interconnecting means can serve for the mounting of lenses of a different dimension or style, thus simplifying the production cycles with greater standardisation of the components required.

  • the reference 1 indicates as a whole a pair of spectacles produced according to the present invention, comprising a mounting 2 to which a pair of lenses 3 are connected by means of interconnecting means of the strap type.
  • the mounting 2 comprises a pair of respective mounting members 3a, each of which extends in an arc in the region of the eyebrow arch.
  • the members 3a are connected to each other by an intermediate bridge 4 located in the central nasal support region and are in turn connected, at their opposed lateral ends, to respective support arms 5 for hinges 6 for the articulation of mounting arms 7.
  • the hinge supports 6 are also known by the term "lug" in the relevant technical field.
  • the members 3a are further provided with respective nasal support pad, indicated as a whole by 8 in the figures.
  • the mounting members 3a are shaped so as to surround, closely following the shape thereof, corresponding portions of the edge of the respective lenses 3.
  • Each mounting member 3a is further provided with a groove 9 running along the entire length of the mounting member 3a and open in a position facing the lens thickness. Said groove 9 is moreover open at its respective opposed ends.
  • a respective flute 10 is also provided, arranged for the connection, by strap means, to the corresponding mounting member 3a, as will be clearly revealed in the continuation of the description.
  • the flute 10 has in cross-section a circular arch profile or, as an alternative, another profile variable in general.
  • the strap interconnecting means comprise, for each lens 3, a single segment of strap 11, conveniently made of resiliently extensible material, for example of plastics material or materials having similar characteristics of resilience and flexibility, also comprising among them metallic materials.
  • the strap 11 may advantageously be made of nylon, by means of injection moulding technology or by hot forming in a coining die or extrusion processing.
  • the segment of strap 11 comprises at least two segment lengths 11a, lib, extending in prolongation of each other, and having a different cross-section.
  • the profile of the cross-section of the first length 11a is defined by a first and a second profile part, respectively indicated by 12a, 12b and connected to each other in a region of restricted intermediate cross-section, such as to impart to the entire cross-section a configuration which recalls, at least at a first approximation, a substantially figure-of-eight shape (Figure 12).
  • the profile of the cross-section of the second strap length lib has substantially the shape of the second profile part 12b, with the exception of the aforesaid connecting region, and preferably has a circular shape (Figure 16).
  • the cross-section of each of the strap lengths 11a, lib is constant in the respective direction of longitudinal extension of the corresponding length.
  • each lens 3 For the connection of each lens 3 to the mounting 2, provision is made for the first strap length 11a to be retained by engagement in the respective groove 9 of each member 3a, and for the entire strap segment 11 to be extended to surround the peripheral lens edge by means of engagement of the second profile part 12b in the flute 10 of the lens.
  • the locking of the lens on the mounting is obtained, as will be explained in detail hereinafter.
  • coupling means are provided, comprising a pair of adjacent holes 13a, 13b passing through the corresponding member 3a.
  • Said holes are preferably located, on the member 3a, in proximity to its end adjacent to the intermediate bridge 4, and extend axially in a position facing the lens thickness 3.
  • the strap segment 11 is initially inserted into the groove 9 by the corresponding length 11a, starting from the end of the mounting member 3a contiguous with the lateral lug 5, and by relative sliding between groove 9 and strap 11, the strap segment is caused to engage the groove almost completely, with consequent retention of the strap therein.
  • This retaining action is ensured by the shape of the groove 9, which has, in cross-section, an internal groove cavity 9a, widened with respect to the opening 9b of the groove, so as to hinder the withdrawal of the strap from the groove in a direction transverse to the direction of sliding of the strap.
  • the strap segment 11 subject to determination of a suitable length of the second length lib (and cutting to size of said length, is secured to the mounting member 3a by means of coupling to the pair of holes 13a, 13b.
  • An end portion of the strap length lib is inserted into the hole 13a, from the inside towards the outside of the mounting, and is then inserted into the hole 13b, from the outside towards the inside, as clearly shown in Figure 4.
  • the free end of the strap length lib therefore remains partly received in the flute 10.
  • the lens 3 is placed against the corresponding mounting member 3a, with consequent engagement of the first strap length 11a in the corresponding and facing part of the flute 10 of the lens, and is locked by means of extension and engagement of the second strap length lib in the remaining part of the flute 10.
  • the interposition between mounting and lens of the first strap length 11a, having the profile 12b, makes it possible to produce an area of bearing of the lens on the mounting with characteristics of resilient yielding for improved adaptation of the lens (fragile material) to the mounting (rigid material) without the risk of breakage of the lens during the locking of same by means of tensioning of the strap 11.
  • Figure 9 shows a variant of the profile of the groove 9 having a quadrilateral configuration with rounded vertices
  • Figure 10 shows a variant having an approximately triangular configuration
  • Figure 11 shows a variant obtained from a combination of the preceding configurations. It is to be understood that for each preselected configuration of the section of the groove 9, a corresponding cross-section of the first strap length 11a is provided for ensuring engagement of that length in the groove 9 with substantial form fitting.
  • the provision of a more restricted groove opening 9b with respect to the dimension of the inner cavity 9a of the groove further makes it advantageously possible to effect the retention of the strap 11 in the groove even following predictable longitudinal deformations thereof due to the effect of its tensioning, which deformations may include a transverse reduction of the strap section engaged in the groove.
  • each lens a single strap 11 is provided (whether with open or closed contour, as described hereinafter), and that each lens is mounted as described previously with specific reference to only one of such lenses.
  • the strap segment 11 in which details similar to those of the preceding example are designated by the same numerical references, provision is made for the strap segment 11 to be shaped in a closed ring, as clearly shown in Figure 7.
  • cross-sections of the first strap length 11a similar to those of the preceding example are provided, for example those provided, as an alternative to one another, in Figures 12 to 15, with the provision of corresponding cross-sections of the groove 9 provided in the mounting member 3a ( Figures 8 to 11).
  • the strap 11 may advantageously be secured to the mounting without any provision of coupling means with through holes, such as those described in the preceding example.
  • a suitable choice of the dimensions of the ring in fact makes it possible to obtain in the tensioning of the strap the necessary forces for locking thereof against the lens without the need for auxiliary means for securing the strap itself.
  • the same ring of strap may be used for mounting lenses of different styles and dimensions, thus facilitating and simplifying the cycles of production and assembly of the spectacles.
  • spectacles according to the invention may be obtained with mountings of different materials, in particular, but not exclusively, of plastics material.
  • the invention thus achieves the aims proposed, providing numerous advantages with respect to the known solutions.
  • a principal advantage lies in the fact that with the spectacles produced according to the invention, the structure of the mounting capable of receiving the lens is simplified with respect to the known solutions, at the same time facilitating the operations of the cycle of assembly of the lens on the mounting.
  • Another advantage lies in the greater constructional simplification of the connecting strap that can be produced as a single strap segment having a differentiated cross-section, with consequent reduction of the components and lower production and assembly costs. Yet another advantage lies in” * effecting the connection of lenses of different style and dimension with the same strap connecting means, obtaining an overall reduction of the components necessary for the range of spectacles produced.
